Page 21: Preparations For Measurement - Connection Between The Mm-400B And Measurement Devices
MM-400B (2) Preparations for Measurement – Connection between the MM-400B and Measurement Devices a. Connecting the Toroidal Coil and the Voltage Detection Cable To measure the current or voltage, connect the toroidal coil and the voltage detection cable to the rear panel of the MM-400B. Toroidal coil connector Toroidal coil (e.g., MB-400P)
Page 22 MM-400B • Keep the toroidal coil’s hooking bracket as far away from the welding machine’s arm (secondary conductor) as possible. • Do not deform the circular form of the toroidal coil when fitting it. Do not deform the circular form of the toroidal coil. Keep the hooking bracket at the furthest point from the arm.
Page 23 MM-400B Plug the voltage detection cable connector into the voltage detection cable connector [V-SENS] on the rear panel of the MM-400B. Connect the voltage measurement cables to the electrodes (positive/negative). (Note) To properly perform a voltage detection The voltage detection cable picks up voltage induced by the welding current. To measure the voltage between the tips, connect the cable as shown below.
Page 24: Connecting The Displacement Sensor (Force/Displacement-Equipped Specification)
MM-400B b. Connecting the Displacement Sensor (Force/displacement-equipped specification) As a force/displacement-equipped specification function, the MM-400B can measure displacement.

Current/force sensor MA-770A/771A incorporates a current sensor (toroidal coil), making it possible to measure force and current at the same time simply by applying a force and passing a current.
Page 28 MM-400B Attach the force sensor to the welding machine’s electrodes. When attaching the sensor, be careful with the following: Align the centers. • Be sure that the center of the sensor’s Apply force detection area is aligned with the centers of perpendicularly.
Page 29 MM-400B Attach the current/force sensor to the welding machine’s electrodes. When attaching the sensor, be careful with the following: • Be sure that the center of the sensor’s detection area Welding head is aligned with the centers of Electrode the welding machine’s Clamp the electrodes.

MM-400B f. When Using a Shunt Resistor (Force/displacement- equipped specification) The MM-400B allows for current measurement connecting a shunt resistor connected to the shunt resistor input. A shunt resistor is a resistor for detecting current of a circuit. It is connected in series to the welding current circuit.
Page 33 MM-400B (Reference) Current measurement by a shunt resistor The shunt resistor detects a current in circuit. As shown below, connect it to welding current circuit in series. Be sure to use the shunt with floating off the ground. Since the resistance value changes by heat generation, be careful of use with large current or high duty cycle.

Page 305: Calibration
MM-400B 15. Calibration Regular calibration is required to maintain the MM-400B performance. Calibration is conducted at our facility. For calibration, please send your toroidal coil, force sensor and displacement sensor together with the MM-400B. Depending on the operating environment, the extent of deterioration varies from one MM-400B to another.
